Product Overview
This aluminum alloy bracket is precision CNC machined from high-quality 6061 or 7075 aluminum (customizable), offering a perfect balance of lightweight design, strength, and excellent machinability. It is designed for assemblies requiring reliable mechanical support and stable alignment.
Widely used in mechanical linkages, automation systems, fixtures, and custom CNC aluminum parts, this bracket ensures high performance and durability in demanding industrial applications.
Product Construction
The bracket is manufactured as a single-piece aluminum alloy bracket, providing high structural integrity and eliminating assembly tolerance errors. Its reinforced flat base ensures stable mounting, while the upper section integrates dual shaft ears formed with 5-axis CNC precision machining.
Each ear includes a concentric bore with tight tolerance control for smooth rotation or accurate shaft alignment. The transition area between the ears and the base plate is smoothly radiused to reduce stress concentration and improve load distribution.
The base includes four countersunk mounting holes for flush installation, minimizing interference. The brushed surface finish enhances visual appeal and friction characteristics, making it suitable for mechanical contact applications.
